Abstract
Complexes of VO(IV), Zr(IV) and UO₂(VI) with 2-hydroxy-5-bromo-3 nitro acetophenone hydrazone Schiff base derived from 2-hydroxy-5-bromo-3-nitroacetophenone and isonicotinoyl hydrazide have been synthesized and characterized on the basis of molar conductance, magnetic susceptibilities, elemental analysis, infrared, ¹H NMR, and electronic spectra. The synthesis monobasic bidentate Schiff base ligand commonly coordinates through the oxygen atom of the deprotonated phenolic group and the nitrogen atom of azomethine group. This is confirmed by IR spectral data. The metal complexes have been examined against the growth of bacteria to assess their antimicrobial potential.
